Mark Kayser has a simple message for his fellow hunters: slow down and wait out your prey.
Think like a whitetail. Hell, BE the whitetail. They are infinitely patient creatures, and often you need to wait them out.
In this case, Mark is chasing a buck that has dropped into a coulee in Kansas. He demonstrates his point by not pushing the deer by going in after it. Instead he finds his sniper's perch in a spot he's fairly sure will reveal any movement and lets the clock tick.
